摘要
陆基导航系统应用于弹道导弹组合导航时,将定向波束技术引入到导航过程中,基于标准弹道轨迹计算得到实时变化的定向波束中心方向,并基于干扰弹道讨论了波束宽度的取值范围。该技术避免了广播式通信体制下使用全向天线发射时信号功率较低的问题和问答式通信体制下容易暴露导弹位置的问题,在确保导航精度的同时,提高了陆基导航系统和导弹武器系统的抗干扰能力和生存能力。
When ground-based navigation system is applied to the integrated navigation of ballistic missile, the directional beam technology is introduced to the navigation process. The real time changing directional beam central direction is calculated based on the standard ballistic trajectory, and the value range of beam width is discussed based on the interference ballistic trajectory. Through the application of directional beam technology, the problems of low signal power using omni directional antenna under broadcast communication system and easily exposing missile＇s position under question-and-answer communication system could be avoi- ded, and the anti-interference ability and survivability of ground-based navigation system and missile weapon system could be improved on the premise of ensuring the navigation accuracy.
